I’m doing a tower defense game in Pico8. Puny humans try to kill an ancient immortal that nested on Earth thounds of years ago. As time progresses, units will go from stone age through medieval, modern up to sci-fi. You can evolve and grow limbs in order to kill the attackers.

Sooo… Basic building menu is in. Basic firing and projectiles mechanics are in. Monster projectiles kill the humans but not the other way around 😉 I have the stone thrower, spear thrower and a knight working in game as of now (with 3 more medieval units drawn and animated).
